Abstract
Cross sections of one- and few-nucleon transfers in the reaction /sup 28/Si+ /sup 28/Si at E/sub lab/ -- 151.25 MeV have been measured with a quadrupole-dipole-dipole-dipole magnetic spectrometer. The one-neutron and one-proton transfers to corresponding shell model states in the pairs of mirror nuclei /sup 29/Si-/sup 29/P and /sup 27/Si-/sup 27/Al are found to be approximately equal. The cross sections for few-nucleon transfers to states with excitation energies E/sub x/<5 MeV exhibit a strong enhancement of 1n1p over 2n and 2p and of 2n2p (i.e., 1..cap alpha..) over 2n1p or 1n2p transfers. A distorted-wave Born approximation analysis of the 1n and 1p transfers was performed. The derived spectroscopic factors display a high degree of symmetry with respect to isospin and are consistent with the widely varying values obtained in light ion studies.
